Q1. What are the main types of electrical currents?
Ans. 
The main types of electrical currents are AC and DC.
• AC (alternating current) changes direction periodically and is used in household electricity.

• DC (direct current) flows in one direction and is used in batteries and electronic devices.

• Other types of currents include pulsed DC and sinusoidal AC.

• The choice of current type depends on the application and the equipment being used.
